Check out this guide, I just oc'd my fx-6100 to 4.43ghz stable at 1.45v and I stay under 60 with linx, under 50 with coretemp and under 50 with hwmonitor. But my mobo is a giga ud3 and with that utility it shows above 50 and under 60.

I bought this off dandelioneater, and he also gave me this guide, you can use it and it works!
